Massachusetts’ Congressional delegation signed a letter to Senate and House leadership Sept. 26 asking for an affordability study, a delay in premium increases, a review of the maps to ensure accuracy and an improvement in FEMA’s outreach activities.

“While we support the underlying intent of the legislation,” the Sept. 26 letter reads, “we have grave concerns about its implementation.” It is signed by senators Edward Markeyand Elizabeth Warren, and all eight Massachusetts members of the U.S. House of Representatives (excluding Markey's former 5th District seat, to be filled in a December special election).

In Coakley's letter, she argued FEMA should also be made to do an affordability review related to the new maps. Homes and businesses not previously thought to be in flood-prone areas would be, according to the proposed new FEMA maps.

Coakley and others argue that homeowners and business owners in those areas would be forced to buy expensive flood insurance.
